about

nx_ssh_lib.nx -- shared core of the sovereign SSH-2 client: wire helpers, binary-packet framing, the curve25519-sha256 KEX (fills an SshState with the exchange hash H/session_id + mpint(K)), and the chacha20-poly1305@openssh.com encrypted transport. Composed by nx_ssh_kex (KEX proof) and nx_ssh_client (full session). Bits-up: our own X25519 / Ed25519 / SHA-256 / ChaCha20 / Poly1305. license_tier: ORIGINAL
